How does the relative acidity of 2,3-dinitrophenol compare to that of 2,4-dinitrophenol?
I am assuming that the -I inductive effect in 2,3-dinitrophenol is stronger than in 2,4-dinitrophenol since it operates through less bonds, therefore on inductive grounds it should have a lower $\...

What is the stability order of the carbocation and carboanion?
So I came up with examples as below:
1
2
Now I am confused about the +I and -I effect in these structures since to my knowledge it can only be applied when there is a substituent (I might be wrong)...

Which substitutent should be placed on axial position in SCl2(OCH3)2?
According to Bent's rule, in $\mathrm{sp^3d}$ more electronegative element is placed on the axial position, so between $\ce{Cl}$ and $\ce{OCH3}$ in $\ce{SCl2(OCH3)2}$ which should be placed on axial ...

Does an electronegative atom which carries a negative formal charge withdraw electrons by induction?
Electronegative atoms withdraw electrons by their inductuve effect. Does this fact remain true even when they are heavily loaded with electrons through negative formal charge? Are these two ideas ...

When 2-pentene reacts with HBr, what will be the major product?
If we consider the first step (formation of carbocation by the attack of the proton).
A couple of textbooks I referred say that when the substituents on the $\ce{C=C}$ are different, the direction of ...

Confusions about inductive effect and acid strength
If one of the hydrogens in the alkyl side chain of ethanoic acid is replaced with an atom of Chlorine, the acid has a larger Ka value. My book says this is since the Cl "borrows" electron density from ...

Does hyperconjugation into sigma-star explain methylamine's increased basicity relative to ammonia?
The inductive effect with the polarisation of the C-N bond obviously plays a role in stabilising the positive charge of the conjugate acid. But given the similar electronegativities for C and H, CH3 ...

Why is C2H5 a stronger +I group than CH3?
While reading about the basic character of amines, I came across a note which said that $\ce{CH3-CH2-NH2}$ was more stable than $\ce{CH3-NH2}$ as $\ce{C2H5}$ was a stronger +I group than $\ce{CH3}$.
